TO ALI PERSONS TO WHOM THESE PRESENTS MAY COME:

4 Be it known that I, NATHAN F. CLARK, of Lawrence, in the county ofEssex41 and State of Massachusetts, have invented a new and usefulImprovement in Machinery for Making Roving;l vand Ido hereby declare theseme toibe fully described in the following specifica-tion, andrepresented in the, accompanying drawings, of whch- Figure- 1 is a. sideelevation of a roving-trame. bolster, spindle, and bob'bimgear ordriver, with my improvement applied thereto. v

Figure 2 is a vertical section thereof. i l Y In such drawings, Adenotes a bolster o r spindle-support, and B the spindle, extendingthrough such bolster. C is the driving-gear of' the spindle, and Ethebobbin-driving gear, the latter being arranged on the topi of the4bolster and provided with n projection, D, to sustain the bobbin. Thespindle extends through the gear E and its projection D..

-In carrying out my invention, I make useoi' an anti-friction tube, F,of brass, or other suitable metal. This tube encompasses the spindle B,and extends through the bolster, the gea-rE, and its part D, and risesabove the latter about one inch, so as to enter vend give support to a.bobbin when placed onithe spindle and the top ofthe part D. The saidtube F, I attach to the gear E, so as to revolve with and be revolved byit.

Furthermore,`i`ron1 a eoncavity, a, made in the top of the part D, Ilead a passage, 6,1aterallythroughone side of Athe tube F, and in thatpart of the tube which is within the bolster I torm one or moreholes, c.vThe Vstud to enter the base of the bobbin is shown at cl.' I f When oilis poured into the coneavity a, it will run throu'gh'the passage 6,andfthence into the tube F, and

will lubricate the inner surface of such tube andthe next adjacentsurface of the spindle. Thence the oil will' How through the holes e tothe outer surface of thetube F, and will lubricate that and-the innersurface ofthe bolster. i I

Thus, while the'tube F serves to support the bobhin-gear E on andbymeans of thepbolster, it also answers as a bearing for thespindle,.:1nd t`o givesupport to the bobbin, and prevent the latter frombeing worn by the spindle. Y Y

lIn practice, the bobbinY and spindle-gears are revolved in the samedirection, the spindle` ,being made to revolve a. little faster than thebobbin.

Whenever a tube, F, may become too much ivorn, it may'beeasily removedfrom the bobbin-gear and another tube may be substituted. By meansof thetube F and the oil-passagesV thereof, the lubrication of the spindle andbolster` may be easily eieeted. I

I therefore claim the combination and arrangemerrtof the tube F andbobrbin-rest D, constructed as described, with the bolster A, the tubeF, bavingthe oil-passag`es b and c, for conveying` the oil to thesurface of the spindle and to the interior ot' the bolster,substantially as and for the purpose set forth'.
